OneSavings, one of the banks aiming to challenge Britain’s “Big 5” lenders, said underlying pretax profit rose to 78.4 million pounds ($100.19 million) in the six months ended June 30, from 65.3 million pounds a year earlier.

The lender said its loan book grew 10 percent, driven by a 26 percent jump in gross organic origination to 1.23 billion pounds.

OneSavings said it expects full-year net loan book growth of at least a high-teens percentage, with net interest margin broadly in line with 2016 and cost to income ratio mirroring the 28 percent it reported for the first half.

“We are mindful of the macroeconomic environment, primarily driven by uncertainties surrounding the outcome of Brexit negotiations and the potential impact on the UK economy, including some easing of house price inflation, particularly in London,” OneSavings said.
